Its not biased at all, especially since Punks been my favorite wrestler for the last 3 years. Realistically he ain't winning this match, it has nothing to do with bias, its just common sense.
I don't have to know every booker ever to know its straight up a bad idea for Andre to lose to Punk, a guy who although very good isn't mainstream and hasn't made a hundredth of the money or made a hundredth of the impact Andre has for wrestling.
Andre wins because he would always be ahead of Punk in every facet of the business. Frankly, saying its a TLC match so it benefits Punk is the worst argument that could be made because historically it has never mattered. The person who wins in usually the one who is best for business. Andre winning is best for business, Andre was bigger than wrestling, Punk is no where near that and probably never will be.
Its not rocket science, its common sense.
